"In enterprise information technology (IT) environments there is generally an infrastructure team responsible for the operation of hardware, such as servers and storage. The team is also responsible for the operating system virtualization software layer. This team has responsibility for the reliability and integrity of the environment, as well as for the protection of the data it stores. Additionally, there are often one or more database administrators (DBAs) who manage the many tasks related to the data stored in relational databases. This team is concerned with the accessibility, availability, and integrity of this data, which typically includes data protection. Since both teams have a shared interest in protection of the enterprise relational databases, this leads to debate on how this important information should be protected." -- Unedited summary from book.
